[DS-1390] stage 1:  move license, email texts, news out of Configuration Manager.
Oops, missing license headers.
Clean up comments and unused imports.
getConfigurationFile cannot return null anymore.
IDE failed to refactor references embedded in JSPs.
Reintroduce factored-out methods as @deprecated wrappers, so we don't
break third-party code.

These should *not* be mirrored in ConfigurationService.
Manually re-merge UTF-8 changes lost in rebase.
